InterDigital (we interviewed its CEO last week) is selling off around 1,700 wireless patents and applications to Intel for $375 million. The company is making good on its promise to monetize its vast portfolio of IP, including technologies relating to 3G, WCDMA, HSDPA, HUSPA, LTE and 802.11 WiFi connections. It's a short in the arm for Intel's burgeoning wireless arm, which recently outed its first handset, the San Diego. It'll also strengthen the hand of the company in any litigation relating to the technology should the lawyers come knocking. So far it's not clear if the company is retaining an interest in the files its sold off, but we've reached out for comment and will let you know when we do.

Update: The company let us know that it's not retaining any interest in the patents that it's selling off. It also mentioned that the 1,700-strong portfolio equates to around eight percent of the company's overall IP holdings -- a number that it generates roughly every 18 months.
